Fiat Panda Key Fob Replacement
Fiat Panda key fobs contain transponder chips that send an alert to your car to open the doors or start the engine. The fob may stop working for a variety.
The most common cause of key fob failure is a dead coin battery. Other causes include water damages, a faulty module, and interference signals.
Dead Coin Battery
Replace the battery if your key fob is dead. Use a button cell with the same voltage, size, and specification as your old one.
If the key fob was exposed to water, for example a splash of rain or salt water at the beach, it will need to be cleaned before it is able to be used again. The trick is to use a paper towel soaked with isopropyl or an electronic cleaner.
If the key fob has not been exposed to water but still does not work it could be due to an issue with the receiver module or an internal electronic chip. In these cases you can reprogramme the key fob with an OBDII scanner may assist.
Water Damage
If your key fob took immersed in a puddle or pool or even a trip through the washing machine, you could be suffering some water damage. It is usually possible to restore it's functionality by removing the battery and scrubbing the circuit board with isopropyl alcohol. It is best to let the board completely dry prior to installing the battery.
If your key fob has stopped working even after replacing the battery and changing the program, you could have a faulty receiver module. You can find the instructions for changing the programming of most remote keys on YouTube? or in your owner's manual. You could also try resetting the car's onboard computer with the OBDII scan tool.
Faulty Receiver Module
The key fob contains the chip that communicates with the vehicle's system. If the chip is damaged, it can no longer transmit and receive signals to the vehicle. This can be caused by dropping the key fob or due to exposure to water. If the key fob has stopped working after water exposure it may be possible to repair it by cleaning the chip with isopropyl ethanol or electronic cleaner.
If the key fob won't respond to cleaning, it is possible that the receiver module has a fault and needs to be replaced. A damaged receiver module may also cause the remote control key to stop working. This usually happens due to electromagnetic interference.
A defective electronic chip
The chip inside your key fob is a vital role in the anti-theft security system of your vehicle. It transmits a signal to the immobiliser unit of your vehicle to tell it whether or not the key is legitimate. The car will not start in the event that the chip has been damaged.
A defective chip could be caused by interference from other objects, weather conditions or transmitters located near your vehicle. In this case you'll need an entirely new key fob.
Faulty Battery Contacts
The battery contacts inside a key fob are very delicate and could be damaged with hard usage. If they are bent, or broken, the fob won't send any signals to receiver modules inside the vehicle.
Modern fobs are constructed with rubber seals to keep out water. In the event of submerging them in water, even if it's just the slightest splash or drizzle can harm the electronic chip.
The key fob is equipped with the chip that connects to the vehicle's immobilizer system in order to start it. The system relies on cryptocoding systems in newer vehicles or the red key system for older ones. If the chip is damaged it must be replaced.
Faulty 12 Volt Battery
A defective battery can cause the key fob to function. The car's computer may not recognize the remote if this occurs.
Test the battery with the help of a voltmeter to determine its capacity. A fully charged battery will display 12.6 volts. If the reading drops significantly it's time to change it.
Put an electrical load for a short time on the battery to check its capacity. This will eliminate approximately 1 percent of the charge on the surface. After that, measure the voltage. The higher the capacity of the battery and the longer it can maintain its voltage. It is ideal to maintain at or near 12 volts for several minutes.
Radio Signal Faulty Radio Signal
This is the most frequent reason for keys not sending signals to cars. The issue can be fixed by replacing the battery. It is however important to purchase a battery that is the same size and voltage as the original one.
The buttons are not impervious to destruction and can withstand a lot. The battery contacts and buttons are delicate which means they could be bent or damaged by rough usage.

A signal may also be impacted by other objects or transmitters which use the same frequency. A light-control system in your home, for instance could interfere with key fobs that use the same frequency. This can affect the remote control of your car.
Incorrect OBDII scan tool
There are many reasons why scanners don't work. Some are more complex than others.
Professional scan tools enable mechanics to look over the car's network and run various self-tests. These tools can save you a lot of time, but they are costly and out of reach for most DIYers.
If your OBD2 scanner isn't turning on examine the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If https://www.g28carkeys.co.uk/fiat-car-key-replacements-near-me/ is fine there is a chance that a fuse has failed. This is the most typical cause of scan tool failure. The easiest solution is to replace the fuse that has been blown.
